Declared nutrient
The amount of the vitamin or mineral in the intended serving. For minerals, this is distinct from the weight of the compound supplying it.

Useful details to include
- The formula
- Nutrients and amounts per serving, preferred ingredient forms, or your existing composition.
- The customer’s serving
- Preferred capsule count and any shell requirements.
- The finished product
- Target countries, pack format, capsule count per pack and expected order quantity.
- What you already have
- Ingredient specifications, current label or supplier documents, if available.
The formulation decision that changes the servingThe nutrient on the label
The nutrient on the label
is only the starting point.
“Magnesium” names the nutrient. It does not identify the exact compound, concentration or physical grade to buy. Those choices affect how much material goes into your blend, and how much space it needs.
Weighed material
The quantity of the selected ingredient needed to supply that nutrient. Its concentration and specification determine the relationship.
The complete fill
All the materials in the blend, including any excipients. Their combined volume helps determine capsule size and capsules per serving.
The same nutrient target can lead to a different capsule serving. Compare the actual ingredient grades and the full blend before fixing the pack count or artwork.

Same calcium target.
Different ingredient weight.
A source with a lower calcium concentration needs more material to supply the same amount.
200 mg calciumHypothetical calculation target
Calcium carbonate40% calcium
200 mg ÷ 0.40≈ 500 mg source material
Calcium citrate21% calcium
200 mg ÷ 0.21≈ 950 mg source material
Rounded from the reference concentrations in the NIH calcium fact sheet. A calculation, not a dose recommendation or a list of materials stocked by TS LAB.
More material does not tell you the capsule count. Confirm the actual supplier assay, complete blend and measured density before choosing the capsule size and serving.

One nutrient or a full blend.
Make the serving work.
Each project starts from what your brand wants to sell. A single-nutrient product and a multivitamin need different formulation decisions.
Single vitamin or mineral
Choose the source.
Then define the serving.
Bring the nutrient target and any preferred ingredient form. Review the selected material, the amount required and the capsule count that suits the product.
Explore ingredient sourcingMulti-ingredient formula
Build the complete blend.
Then assess the fit.
List every ingredient and the amount you want per serving. Assess the complete blend against the capsule size and number of capsules your customer will take.

Make the market part of the brief.
- Where it will sell
- Name the countries so the source, label and notification requirements can be reviewed.
- Who it is for
- State the intended customer group. Age and intended use belong in the assessment.
- The daily serving
- Set nutrient amounts and capsules together, before settling the pack count.

The factory behind your formula
Keep the product and its production connected.
Formulation, capsule filling and packaging belong in the same conversation. TS LAB fills supplements into hard capsules and offers jar and blister packaging at its production site in Slovenia.
- 01
Set the product brief
Nutrient targets, ingredient preferences, target market and intended serving.
- 02
Define the formula and fit
Exact materials, blend quantities and capsule format, with development or sample work scoped to the project.
- 03
Connect the serving to the pack
Capsules per serving, count per pack, jar or blister format and order quantity.

Before you send a brief
Vitamin & mineral manufacturing questions.
Practical answers for comparing options and preparing your product brief.
Why can powder weight exceed the declared mineral amount?
A mineral is supplied in a particular compound or preparation. The material quantity needed depends on its nutrient concentration; the complete capsule fill can also contain other ingredients. Assess the selected grade and the full formula, rather than treating the declared mineral amount as total fill weight.
Can you work from my existing vitamin or mineral formula?
Send the complete composition, current specification and intended markets. Material availability, manufacturing suitability and any proposed changes need to be assessed before a transfer is agreed. Your existing formula is the starting point for that discussion.
Can a multivitamin fit in one capsule?
That cannot be established from the product name or declared nutrient amounts alone. The complete ingredient quantities and blend properties determine the volume. Capsule size and an acceptable number of capsules per serving are part of the product brief.
How should I compare manufacturing offers?
Compare the exact ingredient forms and grades, amounts per serving, capsules per serving and finished pack count. Then compare order quantity, packaging, agreed testing and batch documents. A price per kilogram alone does not describe the same finished product.
Does a raw-material certificate establish the finished product’s shelf life?
A raw-material certificate describes that material against its specification. It does not, on its own, establish the shelf life of a finished blend in its selected pack. Agree the supporting evidence, storage conditions and analysis scope for the finished product.
